According to EPA, Masonicare Corp. improperly disposed of PCBs from two transformers through spilling/leakage of PCB transformer oil onto transformer cabinets, the concrete pads that the transformers stood on, and the nearby ground. Masonicare also failed to properly register and label both PCB transformers.

Masonicare has since sent the two PCB transformers to a disposal facility authorized for PCB waste and has completed remedial work on the contaminated soil.

PCBs are persistent in the environment and are suspected carcinogens. Exposure to PCBs can cause liver problems and skin rashes.
